Euro Spallucci, Anais Smailagic
A regular black hole model, which has been proposed by Hayward, is
reconsidered in the framework of higher dimensional TeV unification and
self-complete quantum gravity scenario (Dvali, Spallucci). We point out the
"quantum" nature of these objects and compute their cross section production by
taking into account the key role played by the existence of a "minimal length"
l_0. We show as the threshold energy is related to l_0. We recover, in the high
energy limit, the standard "black-disk" form of the cross section, while it
vanishes, below threshold, faster than any power of the invariant mass-energy
\sqrt{-s}.
